hey all! we've got an 07 grand vitara xsport and it's quite a fun little vehicle, way different than my colorado. i'm quite new to the whole suzuki thing so don't bash me to much

i'm really into getting the most out of my vehicles but i've run into a snag with these vehicles, the same way i did with the colorado. i've been having trouble finding good aftermarket performance pieces for this vehicle. really looking for 2 basic parts, intake and exhaust. does anyone have any good tips on building my own intake or is there a cai out there (like kn or injen)? and exhaust... i'm used to truck exhaust which is pretty straight forward but i was looking underneath the gv yesterday trying to get ideas, and it looks like the exhaust system goes every way but straight back. any suggestions on a new muffler or setup?
thank you for all your help in advance and hope to learn lots for you all!
